Cycle Life: > 2000 cycles at 100% Depth of Discharge (DoD), up to 5000 cycles at 80% DoD. Features of lithium iron phosphate battery.The cycle life reaches more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. The performance-price ratio will be more than 4 times that of lead-acid batteries. Lithium iron phosphate has undergone strict safety tests and will not explode even in the worst traffic accidents. The peak value of lithium iron phosphate electric heating can reach 350. While lithium manganese oxide and lithium cobalt oxide are only around 200. Small size and light weight. Green environmental protection, regardless of production, use and scrap, does not contain or produce any toxic and harmful heavy metal elements and substances. The self-discharge rate is very low, which is one of the most outstanding advantages of the battery. Generally, it can be less than 1%/month, less than 1/20 of the Ni-MH battery. Built in Automatic Battery Protection System Internal. The intelligent, electric Battery Management System(BMS) protects batteries from extrem temperatures, overcharging, and excessive discharge, provide short circuit protection, balance voltage each cell. 1x 12v 200A LiFePO4 Battery Pack (Charge and discharge from the same wires). This pack doesn't include the charger. It is recommended to charge up the battery to 80% if you are going to store it for a period. Make sure the battery will be charged at least once every 3 months to ensure the best performance and cycle life. The battery should be stored in a dry environment, keep away from fire and heat sources. Avoid direct connection of positive and negative poles.
